Both the G17 and G19 are iconic pistols that have been around for almost 40 years, but if you really had to pick, which one should you carry?
Based on outward appearances, there is very little difference between the two models, but we delved a little deeper into the question.
Looking at the stats, it’s obvious that the G17 is longer, but bigger isn’t always better.
We combined a lot of personal experience with a unique range session comparing the two guns to provide you with a definitive answer.
So keep reading, as we run through each gun’s specs and features and take them to the range for a head-to-head comparison.

How We Tested and Compared the G17 and G19
For this review, we used a Gen 5 G17 and a Ge n5 G19 MOS. Both guns were reverted to stock configuration.
We utilized standard Glock sights for accuracy and did not use any type of optic. Accuracy was established by shooting 10-round groups at 7 yards using 115 gr AAC 9mm ammo.
We also tested the trigger on both guns with a Lyman Digital Trigger gauge to get an accurate assessment of the actual trigger pull weights.
Additional testing consisted of mounting a Surefire X300 weapon light to each gun and drawing from a PHLster Floodlight carried AIWB for drills. Performance was measured with a Shooters Global SG Timer.

Glock 17 vs Glock 19 Background
Gaston Glock invented the G17 (named for its patent number, not capacity) in the early 1980s. The plastic fantastic took the Austrian military by storm after surviving a grueling torture test.
Soon after, Austrian police took notice and began to adopt the new wonder gun with a polymer grip.
In the early days, there was actually some drama surrounding Glocks. When they came to America in the mid-1980s, some government agents tried to push the idea they could pass through metal detectors because they were mostly polymer.
These flames were fanned in Die Hard 2 when the main character identified a “Glock 7” made of porcelain that could also pass through metal detectors. All the furor led to the passing of the Undetectable Firearms Act of 1988, requiring guns to have a minimum of 3.7 oz. of metal.
The legislation ensured something that was already happening, and the Glock 7 was a myth. No working Glock could ever pass through a metal detector undetected because the slide and barrel are made of metal.
Despite the borderline lunacy of 1988, Gaston Glock kept trucking and even created a new model, the G19. This slightly scaled-down version of the G17 traded some capacity for a more svelte approach.
Both the G17 and G19 continued to evolve over the following decades, and many new models were added. In fact, there are now five generations of Glocks and over 50 models in different sizes and calibers.
(You can dive more into the history of Glock here!)
The first gun I purchased was a Gen 1 G17 back in the 1990s (I wish I still had that gun). However, I was entering the ranks of law enforcement and would spend much time with Glocks in the ensuing years.
Throughout much of my career, I trusted and used Glocks, either on or off duty—whether my assignment was Patrol, SWAT, or Search and Rescue. Eventually, I became a firearms instructor for my agency and a certified Glock armorer.
All this to say emphatically, I have a lot of experience with Glocks, particularly the G17 and G19. And I definitely have some thoughts on which is the better gun to carry.
Who Are the Glock 17 and 19 For?
As a general rule, the G17 serves well as an open carry or even duty-related handgun because of its size and utility. This isn’t to say the firearm can’t be concealed because it can.
Anyone from the home defender to security guards or law enforcement would do well to select such a solid pistol. Adequately accessorized, the G17 serves each of these roles perfectly well.
On the other hand, the G19 can also serve in these roles equally well, although it has slightly less capacity. The size difference, although slight, makes the G19 more favorable to those who want to carry concealed.
Ergonomics: Fit & Feel
While Glocks are widely known for their reliability, their brick-like shape has often caused people to lament their ergonomics.
While the shape of the slide really doesn’t matter that much, the blockiness of the grip tends to lose some points in ergonomics.
The G17 has a larger overall frame, which allows plenty of room to establish a good grip. In addition, the support hand also has ample room to complete that grip.
In comparison, the G19 has a slightly shorter grip, so the distance between the top of the backstrap and the bottom of the magwell is shorter. While it still fits a wide variety of hand sizes, there is a little less room.
It should be noted that the G17 has a grip that is roughly four inches tall, measuring from where the slide mates to the bottom of the magwell. Conversely, the G19’s measurement is approximately 3.5 inches.
Hand size matters when selecting a G17 or G19 sidearm. Anyone with big mitts should use an extended beavertail to avoid a potentially painful problem.
The shape of Glock’s grip can cause the webbing of the hand to push up over the backstrap. In turn, this allows the back of the slide to strike the hand with each shot — known as slide bite.
It is a very real issue, though I often hear it discussed as some sort of range myth. I have scars on my right hand from early model Glocks (or Glocks without extended beavertails).
Thankfully, with the fourth generation, Glock introduced several interchangeable backstrap options for various hand sizes. At least two of them included an extended beavertail.
Regardless of hand size, both the G17 and G19 offer serviceable grips, though there are more ergonomic options out there. Either option will work, though the G17 has the advantage of having more room.
Texture on the grips is light, though adequate. A series of raised squares covers all four sides and keeps the Glocks in your hand even when wet.
And again, while the overall shape of the grip is blocky, the backstrap is nicely curved and helps lock the gun in with a high grip, as does the undercut on the trigger guard. The curve fits the swell of the palm and is even more substantial with an extended backstrap.
Controls
I’m not going to beat around the bush about Glock triggers; they don’t have a great reputation. That said, the Gen 5 triggers are my favorite — definitely the best out of the bunch.
(Learn more about the different Glock generations in our guide!)
One of the issues identified with them is a squishy pre-travel up until you hit the wall, followed by a bit more compression before they break. This issue is present in older models, though I feel the Gen 5 has improved.
The actual break is fairly crisp for a striker-fired gun, and the reset is great. I like the audible and tactile nature of the reset on Glocks.
The triggers in the G17 and G19 are the same, so there isn’t much point in comparing these two models in this area. Glock lists their trigger pull weight at 28 Newtons, which converts to 6.29 pounds of force.
Using the Lyman Digital gauge, I measured my test models, and the G19 averaged 5 lbs. 8.4 oz. The G17 averaged 4 lbs. 13 oz. but has a higher round count.
(If you hate the trigger, you can always swap it out for an aftermarket variety. We did some extensive testing on Glock triggers using a Dvorak Trigger Scan unit in our Best Glock Triggers round-up. )
Both guns also benefit from an ambidextrous slide stop/release that is a little easier to reach in the Gen5 variants. The last issue to discuss is the magazine release.
Although it’s serviceable, I have to break my master shooting grip to activate the button. I have seen extended mag releases that make this unnecessary, but they sometimes conflict with holsters and can release your mag when you don’t want it.
Again, these are the same in both models. Glocks’ modularity is a great benefit, particularly to organizations that must field several at a time.
How Do the Glock 17 and Glock 19 Shoot?
For this breakdown, I tested both guns in a few categories that made sense to end users. My goal was to find definitive answers based on factual data to help me declare a winner between the G17 and G19.
Reliability
This category wasn’t specifically tested during this session, but I’m relying on years of experience with Glocks. They are very reliable, but they aren’t infallible.
Accuracy
I fired 10-shot groups at a paper target from seven yards, using only the iron (plastic) sights to establish accuracy.
While the G17 has a slightly longer barrel than the G19, this doesn’t make it any more accurate. Taking my time and carefully breaking each shot, I fired ten rounds of AAC 115gr FMJ through each gun.
The results were so close I wasn’t really able to tell with the naked eye so I measured them with calipers. For the G17 all shots were in a group roughly 1.52 inches while the G19 grouped 1.42” inches.
Considering I was the main variable in this equation, I interpreted this result as somewhat of a draw. I could probably shoot this multiple times and share results back and forth between both guns.
Velocity
One area where a longer barrel actually does make a difference is velocity. The G17 comes with a 4.49-inch barrel, which is 0.47 inches longer than the G19’s 4.02-inch barrel.
I used a Garmin Xero C-1 Pro chronograph to test velocity and fired ten-shot groups of AAC 115gr FMJ to obtain average speeds. With a half-inch barrel length difference, I wasn’t expecting much change.
Interestingly, the G17 averaged a speed of 1209.4 FPS compared to the 1133.9 FPS average from the G19. The G17 takes this hands down, but that really isn’t much of a difference.
Concealment
Another area I wanted to test was seeing how both guns concealed and how they drew from concealment. To keep things on a relatively even playing field, I mounted a Surefire X300 light to each gun and holstered them.
The holster I used was a PHLster Floodlight. It is designed to index off of the light and isn’t completely reliant on the shape of the gun, so a convenient way to fit both the G17 and G19.
Donning the Floodlight in that AIWB (appendix in waistband) position, I placed the Glock 17 in the holster and draped my t-shirt loosely over it. Against my abdomen, the grip of the G17 felt large and bulky but, surprisingly, didn’t print under my shirt.
However, while moving around the range, I noticed how bulky the G17 felt. If I twisted it, it printed pretty clearly and was more visible.
In addition, simple movements that I’d take for granted otherwise became more difficult. For instance, bending over to pick something up was challenging as the bulk of the G17 would press into my body painfully.
The Glock 19 in the same holster concealed a little better, disappearing under the t-shirt. Even with a twist, it wasn’t as visible thanks to the shorter grip length.
In contrast, moving around with the G19 holstered was a lot more comfortable too. Even though the size isn’t that much different, there was a noticeable increase in comfort and range of movement.
Draw
When comparing the draw from the Floodlight, two areas loomed in my mind. I thought the G17 might be easier to grab and establish my master grip, but I reasoned the shorter length of the G19 might make it quicker to present.
The only way to find out was to test, so I loaded up each gun and conducted a series of drills. At seven yards, I drew and fired three rounds from the holster as fast as I could.
Using an SG Timer, I started out fairly slow and began to push myself as my comfort increased. With the G17, my times were just over two seconds on average.
I then switched to the G19 and ran the same drill. Initial times were just under two seconds and even dipped down to 1.72.
Part of me thought the G19 might be faster, but I switched back to the G17 to test another theory. Running at the same pace, my times with the G17 turned out to be around 1.7, too.
In essence, I couldn’t determine a faster draw with either gun. Since I was the variable in the equation, draw and shoot times averaged the same.
While I found the grip of the G17 easier to grab at first, the grip of the G19 wasn’t much different. My hand felt a little more cramped on the G19, but there was still ample space.

Glock 17 vs. Glock 19: Final Verdict
Sifting through a couple of decades with both guns and focusing my thoughts on the most recent testing, I came up with a few solid conclusions about which gun is better. The results fit categorically with my findings.
The tests I conducted revealed similar performance between both guns. Accuracy, draw, and velocity were close enough to be negligible, so I weighed other factors.
The Glock 17 has advantages because of its size. The capacity is slightly better and there’s just more room to get both hands on the gun — especially for bigger-handed shooters.
Accordingly, the G17 edges out the G19 for open carry, duty carry, and perhaps even competition. However, the G19 isn’t out of the running.
Undoubtedly, the Glock 19 is easier to conceal and is more comfortable to wear while doing so. Despite losing a couple of rounds of capacity, the tradeoff is well worth it to the concealed carrier.
The G19 is small enough that it’s more comfortable to wear, but it is still big enough to be an effective pistol for defense. Plus, you can probably still tie your shoes while concealing one.
Both guns can serve in either role and make great home defenders, but each shines in its respective categories.

Ahem... to start with, I prefer a 10mm. I have no shooting issues in either a G20 or G29. Obviously, the G29 is easier to carry concealed plus an extra mag in reserve. In 9mm, I have a G23 with a KKM conversion 9mm barrel, essentially making it a G19. I love it (also have a KKM conversion barrel in .357Sig). Flexibility and a huge aftermarket is the BIG plus with Glock. There has never been a firearm made that is 100% perfect for everyone. If you look hard enough, you can a design flaw of some degree in anything. That said, try before you buy if you can. Some gun sellers here in Texas let you rent a firearm, shoot at their range (often indoors), and make an empirical decision. Don't let test reports, ads, or price be the sole variable in the decision to purchase. Make a good purchase decision, then practice and make it YOUR firearm. I have one firearm (unmentioned) that I purchased that I shoot very well, yet others balk at my buying one and claim they cannot shoot it at all. Me? I love it. Manage your expectations and remember: to each his own.
If you can afford one. Five stars for being made in TEXAS!
I will thanks for the information!!
Being a smaller framed guy I love the G19. But when it comes to EDC, I carry the G48 with aftermarket PSA Micro 15+1 magazines. The magazines have always worked flawlessly in my G48 and gives me the same capacity of the G19. It's somewhat slimmer frame is a plus for me due to my size. I also have the G43X but for conceal carry, I still lean more towards my G48. Even though the G43X is a tat smaller. I haven't figured out why, personal preference I guess, but the G48 with PSA mags is my go to conceal carry.
BTW this article was a really good comparison of the G17 & G19. I love reading y'all's articles and this is the first time that I recall ever commenting on them.
STACCATO-one and done!!!
Hello, I own 3 Glock’s 17, 20, 26, and I love all 3. I did upgrade the guts on all of them, and the triggers to a 3Lb pull and crisp. So nice. My carry is the 17 and @ times I have carried the 20.
Great articles, love it!!
Aaaaw shucks fellaws, I got the best of both worlds with a g45!!! Lol I like m all actually anything that goes bang. Great info...
Thanks Robert! You're absolutely correct, finding the carry option that works for you is the goal.
Although I don’t really care for Glocks; this was a very good article on them. May be I’ll give them another look. My son has a G 45 and he likes it.
Thank you! As I pointed out, Glocks are not without their faults, but they have some strong qualities too. We're lucky to have so many good options to choose from.
Great writeup and comparison. What are your thoughts on (seemingly) combining the two in the 19X?
Thanks Chris. The G19X is a great option. I have bigger hands so prefer a bigger grip in general. However, it may not conceal as well. I'm glad Glock gives us so many options to choose from.
What do you think of the G49?
I haven't put my hands on one but I understand the concept. I suspect it would be a great option though I would want to confirm the extra barrel didn't slow my presentation like I did in this article.
Fine article...but...When I carry, it's a Gen 2 Glock 21 with uncountable flawless rounds through it and I wear an oversized jacket heavy or lightweight for the season. If I need a smaller, skinny gun for a really hot day it's a G36 or full size 1911 that slips right behind belt and a (slightly large) tee shirt (I'm not worried about capacity, you don't train to finally hit a target on your 16th 115 grain hollow point) and does not print or gouge when worn on the firing side hip which is where you should carry since most of your training is done from your firing side--keeping it simple when the adrenaline dumps. Movies, work, travel, life, the ATM, the bleaker side of town, a .45, when you're raised on one, you don't need to give it up, either for size or economy, in even Glock's and every other manufacturer's 9mm happy world (If I needed to go somewhere in a tux, and so would have to micro-carry or not carry at all, I'd stay home--there's plenty of opera to stream, and I love the Four Tenors. Or I'd go to the range and celebrate the cartridge.
Thank you Addario. Sounds like you have a carry option for every occasion. The Four Tenors are amazing!
Great article! While I have, and do own, a few Glocks I couldn’t choose between the two which were the subjects of this article. So I said to myself, “Self, you love the fact that the G17 has a 17+1 capacity, but you also love the more concealable size of the G19! What should you do?” So I then said to myself, “Self, you’re a man of the times! You should, and do, deserve the best this world has to offer! And you deserve both variants at the same time!” So I went with the Shadow Systems XR920! And I couldn’t be happier! Done and done!
Thank you Jack, and nicely done! The crossovers really do fill the gap for people who enjoy both.
Wait.
What year is it?
Was this written in 2001?
There are so many better options than these relics from a past century.
I own 2 of each.
They stay in safes.
Checks notes...it's 2025. Lol. We know this is a little outdated in terms of these two pistols being out in the market for awhile, but there are still people who write in and ask us about it. So we do what the people want. Thanks for reading!
That's an astute observation Beef, but many of our readers/viewers are new to firearms and don't have your breadth of experience. Thank you for the read.
Got a G45 to get the best of both! Great article.
Thank you Bartamalu! You absolutely got the best of both worlds in the G45.
Both are very good handguns- this is why I run a G45 ! Thank you for an excellent article.
Hey thanks Pete, appreciate it! I'm glad to see so many readers popping up with the G45 as the reasonable solution to this quandary.
Personal i like the Glock 19, because of the smaller size and easier to conceal
You're absolutely right Jason. Which Gen are you carrying?
A Gen 4, i have a Gen 3 too. The only think I've found is the Gen 4 is harder to find after market upgrades for it.
Very cool. If you haven't yet, check out the trigger on the Gen5s. It's a significant upgrade.
For me short answer, I carry a G22 or a Beretta 92. I am a smaller man, but still prefer a larger pistol.
I tried a G19 and a G26, both print at the back of the slide and the butt of the grip less so, but prints a little there. The G17 rides lower and disappears at the belt line. The G19 & G26 rides lower a bit higher.
Using a G17 holster for the G19 or G26 conceals better in that holster.
When I had an Sig P320 compact, I swapped the grip to make it a carry (17 round) model.
I find my pinky hits the grip right where the magazine baseplate and the grip meet.
For that smaller pistol itch, I say get a G26.
Thanks for sharing Marty. It's all about finding an option that you like.
